APPARATTJ'S FilE STARTING- HEATERS.

Application filed May 19, 1919.

To all about it may concern:

Be it known that I, Roms PODOLSKY, a citizen of the Unitedtltates, residing at Los Angeles. in the county of Los Angeles and State of Californian have invented new and useful Improvements in Apparatus for Starting Heaters, of which the following is a specification.

This invention relates to a timed controlled apparatus for starting heaters, and is more particularly adapted to be used in connection with an alarm clock for start' an electric heate at a predetermined time.

The object of my invention is to provide an ellicient means for automatically starting an electric heater at a predetermined time, and for also sounding an alarm to awake the occupant of the room at a predetermined time utter the heater has been started.

A further object of my invention is to provide an apparatus which will cooperate with an alarm clock, whereby when the clock is set to sound an alarm at a particular time, the heater startinginechanisn'i will be set to start the heater at the same time or at any desired period previous to the time at which the alarm is set.

I accomplish the aboveand other objects by means of the apparatus herein described and illustrated in the accompanying drawings, in which:

Figure 1 is a back view of any well known type of alarm clock showing my improved appa 'a'tus applied thereto, parts being; broken away to show more clearly part of the interior mechanism.

Fig. 2 is a side elevation. of the same, partof the casing being broken away in order that the application of my apparatus may be more clearly understood.

In carrying, out my invention I employ an alarm clock 4, of any well known 'type,.

which is provided with the usual alarm setting stem 5 carrying the pointer 6 adapted to cooperate with the usual dial 7 to indicate the time atwhich the alarn'i is to be sounded.

The shaft 8 which carries the minute hand of the clock and adapted toinake onerevolution each hour, is provided with the pinion 9 which is cut in the surface of said shaft, and consequently revol es therewith. Journaled loosely on the shaft 8 at a point just below the pinion 9 and supported between the collars 10 and 11 which are secured to said shaft, is the annular disk 12, provided Specification of Letters Patent.

Serial No. $98,254:.

with the upwardly extending annular flange 13 which carries on its outer surface the gear teeth 14-, and on its inner surface the gear teeth 15. r

Pivoted loosely around the shaft 8, at a point just above the pinion 9, and held against lateral ncrement between thecollars l6 and 17 which are secured. to said, shaft, is asleeve 18, having a radially ere tending arm 19, which is provid'edwith the downwardly extending; stern 20, upon which is loosely journaled the gear 21, adapted to mesh with the pinion 9 and the internal gear teeth 15. A gear 23 is rigidly secured to the alarm setting stenrii and meshes with the' teeth 14 on the disk 12. l

Formed in the back of the clock, are pair of segmental slots 25 and 26 and disposed in parallel relation. Arranged to slide in the slot 25 is the segmental block 28,'

which carries the pointer 29 adapted to rest upon the outer surface of the back of thecloch: and cooperate with the graduation i'narks 30, which represent fractions of an hour in quarters. The block 28 also carries" an arm 31 adapted to rest upon the inner surface oi the back of the clock, which in turn is provided with an electric cont-act brush 3:2 properly insulated therefrom. Threaded into the arm 31 and passing outwardly through the'slot 26 is the knurled headed screw 33.

'By the above described arrangement it will be clearly seen that when. it is de ed to move the pointer 29 to register with any of the graduation marks 81, it will be only necessary to loosen the screw and more the block 28 around in the slot until reaches the desired point and then tighten the screw again. i

Referring to Fig, 1, 35 represents the power lines connected to any suitable source of electrical energy. The brush 32 is 'connected to the positive side of the power line by the wire A brush 37 adapted to wipe against the shaft 18, is secured to a post 38 mounted on the back of the clock; and a wire 39 runs from said post to electric mag netic coil 40, the free end 41! hf said wire terurinating at a contact button 4. An armature 43 adapted to cooperate with the coil 40 is pivoted at 44: and is provided on its end with the brush 4-5 adapted to normally contact with the button 42. Another-contact button 46 is arranged in the path of the nand has a wire 4:7 leading'there "ill rec

from to, an electrical heater i8,.shown in diagram, which in turn is connected to the positive side of the power line by the wire 49. The arm 19 is provided with a contact finger 50 adapted to engage with the brush 32 at predetermined intervals.

\ The operation of my apparatus is as follows; The alarm mechanism is set in the usual manner, by moving the pointer 6 in :10 the direction indicated by the arrow A to the desired hour at which the alarm is to be sounded, and in so doing the gear 23 actuates the gears 1%, and 21 to move the arm 19 an equal number of degrees in the direc- 15"-tion indicated by" the arrow B, said gears being properly proportioned for this pur pose; ,The inion 9 on the minute hand shaft 3 meshing with the gear 21, causes the arm 19 to move in the direction of the arrow 20 B one-twelfth of the cycle every hour, the gear teeth 14 and 15 being locked against movement by the ear 23 for this purpose. As illustrated in l ig. 1 the time of day is twelve oclock and the alarm is set to sound 25 at six oclock, it will therefore be seen that when the hour hand has reached six oclock the alarm will be sounded and at the same time the arm 19 will have advanced just onehalf of its cycle, until the contact point 50 39 secured thereon engages with the brush 32, thereby closing the electric circuit through the magnetic coil to shift the armature 43, thus closing the circuit through the heater 48. When it is desired to close the ciras cuitthrough the heater at any time previous 1 z. to the time the alarm is sounded the pointer 29 and brush 32 are moved in the slot 25 to an advanced position. Thus it will be seen that the heater may be started at any 40 predetermined time previous to that at which the alarm is sounded.

It will be seen that by the foregoing description that I have provided a simple and efiicient apparatus whereby an electric heater d5 may be automatically started at any predetermined time and may be located in any desired room or part of the building other than the room in which the alarm clock is located, thus warming the room previous to the time the alarm of the clock has sounded to awaken the sleeper.

What I claim is: I

1.' An apparatus of the class described, comprising means for sounding an alarm,

and means cooperating with said alarm for 55.-

starting a heater at any predetermined interval from the time the alarm is sounded.

2. The combination with an alarm clock provided with alarm setting mechanism, of

means associated with said alarm setting .justed to sound the alarm at a prcdctermined time, the contact switch and brush will coiiperatc to close the electric circuit to start the heater at a predetermined interval from the time the alarm has sounded.

4. The combination with an alarm clock provided with alarm setting mechanism, of a heater interposed in an electric circuit, of a switch in said electric circuit mounted on the shaft of the minute hand of said clock and adapted to normally move with said shaft, of mechanism interposed between said switch and said alarm setting mechanism whereby said switch may be moved on said shaft in exact ratio to the movement of said alarm setting mechanism, and an adjustable brush interposed in said electric circuit and disposed in the path of said switch whereby when said brush and switch contact, the electrio circuit will be closed to start said heater.

In witness that I claim the foregoing I have hereunto subscribed my name this 8th day of'May, I919.
